10 WATER DISTRIBUTION SYSTEM Component Capacity Condition Funding Future Need O&M Public Safety Resilience Innovation Average Component Weighting Weighted Value Distribution % Water Meters % 2.07 Weighted Average 100% 50.6 Overall C The City's water distribution system is comprised of over 200 miles of distribution mains ranging in size from 2 to 20 inches, 3,941 valves, 973 fire hydrants and over 13,000 service connections. The current efforts of the water main replacement program has resulted in over 30,000 linear feet of distribution mains replaced in the past 3 years. In house crews conduct preventative maintenance measures on each fire hydrant annually to ensure fire protection for the citizens and business owners. The City's water distribution system has over 13,000 potable water service connections ranging in size from 5/8" to 6". The meters are read by in house meter readers. Approximately 56% of the system meters are greater than 10 years old and approximately 23% are more than 20 years old. As meters age they tend to deteriorate due to sand and particulates in the water which results in inaccurate and typically low recordings of water consumption. This makes it difficult for a utility to understand water consumption behaviors, institute water conservation measures, detect water losses and leaks, and appropriately charge customers for water usage. Currently meters in areas of water main construction projects are being evaluated and replaced as necessary.
